image processing - How to compute features using DAISY feature extractor? -

i wondering if has used daisy features object recognition problems?

link daisy (matlab one) is: http://cvlab.epfl.ch/software/daisy

my question how use software (matlab) keypoints , descriptors? can found out descriptors (in dzy.descs), cannot found keypoints.

i want give try technique object recognition, since, has been written computation fast , produce better result.

thanks lot.

daisy designed dense point matching, means computes descriptor every pixel in image - that's designed do. could retrieve features particular pixels in image using display_descriptor function described in documentation:

out = display_descriptor(dzy,y,x); 

where x , y pixel co-ordinates. use keypoint detector of own (e.g. corners, blobs, sift keypoints - see blob detection on wikipedia) decide features extract. should bear in mind not intended use of daisy.
